MOLD FOR MAKING PIG-TROUG'HS.

Specification of Letters Patent.

Patented May 8, 1917.

Application filed January 27, 1917. Serial No. 144,907.

To all whom it may concern:

Be it known that I, JOHN KRoNsER, a citizen of the UnitedStates, residing at Apple ton, in the county of Outagamie and State of Wisconsin, have invented certain new and useful Improvements in Molds for Making Pig-Troughs, of which the following is a specification.

This invention relates to certain new and useful improvements in molds for making the same.

One of the objects of the invention is to provide a pig trough of elongated construction that is formed of concrete, cement or similar material with metallic reinforcing bars therein for strengthening the same and with laterally-extending feet at the opposite ends to insure the trough at all times to assume an upright position and obviate danger of the same being turned over.

A further object of the invention is to provide an improved form of mold for forming the trough in which the mold is composed of relatively few disconnected parts, and a device that is extremely simple in construction and operation and one that can be assembled in an easy manner by a single operator if necessary.

A further object of the invention 1s to provide a mold for a pig trough of the type herein disclosed wherein the sides of the mold are bodily disconnected from the remaining structure in assembling and disassembling the parts while the end walls of the mold are hinged to the bottom and carry side extensions which cooperate with the adjacent ends of the removable sides.

With these general objects in view and others that will appear as the nature of the understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and then claimed.

In the drawing forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views Figure 1 is a perspective view of a pig trough formed by the mold herein disclosed.

Fig. 2 is a. longitudlnal. sectional view of invention is better pig troughs and I a mold built in accordance with the present invention, the central portion thereof being broken away and showing in section a portion of the longitudinal core member as well as the reinforcing bars for the concrete.

Fig. 3 is a top plan view of the same with the central portion thereof broken away.

Fig. 4c is a cross-sectional view taken on line IV-IV of Fig. 3.

Fig. 5 is a detail perspective view of one end portion of the mold with the bottom broken away and the sides removed, and,

Fig. 6 is a perspective view of one of the removable side members, with the central portion thereof broken away, and illustrating more clearly the means for removably securing the same to the mold body.

Referring more in detail to the accompanying drawing and particularly to Fig. 1 which discloses the form of pig trough built by the mold disclosed herein, it will be seen that the trou h includes inclined side walls a and which present a trough of substantial V-shape in cross-section while the end blocks 0 carry lateral extensions d which project the desired distance beyond the sides ofthe trough to insure the same assuming an upright position at all times and obviating danger of the trough upsetting.

The mold for forming the trough is more clearly shown in Figs. 2 to 6 and the same being formed of any suitable material, either Wood or metal, includes a flat bottom 10 preferably of rectangular configuration while end walls 11 are hinged thereto as at 12 as clearly shown in Figs. 2 and 5. As shown in said figures, the lower edges of the end walls llrest upon the upper face of the bottom'lO while the opposite ends of the end walls have permanently secured thereto as at 13 inward extensions 14 which lie flush with and engage the opposite sides of the bottom l0. It will be seen that when the end walls 11 are moved on their hinges 12, the inner extensions 14 will be moved therewith to permit the contents of the mold to be readily removed therefrom.

The mold slides are more clearly shown in Figs. 3 and 6 and include main portions 15 having right-angular extensions 16 at 55 mains upon the opposite ends thereof, the outside faces 17 of the extensions being perpendicular to the 7 bottom 10 of the mold 7 are positioned while the inner faces 18 of the sides converge downwardly as shown'in Fig. at to give to the side walls a-: and --b; of the V trough.

In assembling the mold parts, the end walls 11 of the mold are moved to the position shown inFig. 5 and theside walls 15 so that the outer faces 17 of the angular extensions 16 lie juxtaposed to be'observed upon an iiess the mold parts .walls 15, which construction causes the lateral extensions -(Z onithe faces of the end wall extensions 3. v The parts are the inner 1 1 as clearly shown in Fig. held in this position by'the 19 which have the angle ends 20 thereof spaced from the faces 17 'a'distance equal to the thickness of the end wall extensions l l so that when assembled the end wall extensions l l lie between the strap ends 20 and-the side extensions 16 as clearly shown in Fig. 3, and are so gagementl With such as concrete'or cement is placed therein and the central core 21' of substantial triangular configuration as shown in Fig. l is placed therein as illustrated and tends to spread the plastic material in a manner to fill the mold to a point level with the upper edges of the side and end walls, During the process of filling the mold with. the plastic 'material, longitudinal reinforcing bars 22 are placed therein as well as transverse reinforcing bars 23 at the ends thereof It will 7 inspection of Fig. 3 that there is a substantially rectangular pocket formed at each end of. the mold by the end wall inner extensions carried thereby and the angular extensions on the side of the mold end blocks of the trough. v

\Vhen the plastic material has been allowed to set and assume the desired hard are disassembled by first moving the end walls 11 on their hinges 12, which mo-vementcarries' the end wall extensions 14 outwardly of :the mold bot- 60111 10 and from its engagement with the strapsEZO of the side walls 15, and in this position the side walls may be readily removed laterally of the mold'bottoni so that the trough alone containing the core remold bottom. any well known manner, the core 21 may be then remo ed and the completed pig trough re-J .mor'ed from the mold bottom, 10 and 1f necessary, finished in the desiredmanner.

It will be noted that there is provided a i pig trough-and mold for th'esame which is extremely simple in construction and'opera' tion andone that is lnBXPGnSlVG to manufacture and while the desiredincline extensions carried the endwallswith the inner angle iron straps ring in" the same held by frictional en-V the mold partspositioned as described, a quantity of the plastic material the extensions engaging tensions in a manner to present rectangular associated with and side walls, one set of I have shown and de'-' scribed the preferred form of the invention,

it is'nevertheless to be understood that various' forms, modifications of the parts may from the spirit and scope of the invention as claimed. 7 i V 7 What I claim as new is 1.. A trough mold including a bottom of rectangular configuration, end walls hinged the outer lfaces 2.- A trough mold including a bottom, V

end walls hinged thereto, inward extensions carried by the'opposite ends of the endv walls, bodily removable sides for the mold, e'aclisidehaving an angular extension pro.
